根据杨梅对生态条件的要求及杨梅的地理分布,对云南省杨梅生态区划进行了探讨。杨梅树对低温敏感,喜冬季温暖,春、夏季湿润的气候。根据杨梅的耐寒性,极端最低气温、年降雨量及果实成熟时期(5～6月)干燥度的分布,将云南省杨梅区划分为4个区:最适宜区(I)、适宜区(II)、次适宜区(III)和不适宜区(IV)。I和II区适宜于杨梅栽培,在III区应精心选择小气候栽培杨梅,并防御杨梅受冻害。
According to the requirements of Yangmei on the ecological conditions and the geographical distribution of Yangmei, the ecological division of Yangmei in Yunnan Province was discussed. Myrica rubra is sensitive to low temperature, hi winter warm, spring and summer humid climate. According to the distribution of dryness of arborvitae in cold hardiness, extreme minimum temperature, annual rainfall and fruit ripening period (May-June), the bayberry in Yunnan Province was divided into four areas: the most suitable area (I), the suitable area ), Sub-suitable zone (III) and unfavorable zone (IV). Areas I and II are suitable for cultivation of Myrica rubra. In Section III, the cultivation of Myrica rubra should be carefully selected to prevent frost damage on the waxberry.
